Advantages and Applications of Hybrid Cooling

Facilities with a central plant in an area with high on-peak electricity rates and low natural gas prices can benefit from a hybrid approach.  A hybrid plant offers the flexibility of developing a cooling equipment operating strategy that takes advantage of the lowest cost energy option on an hourly and daily basis.   The dual fuel capability of hybrid plants ensures reliable service when continuous operation is critical.  The lower on-peak demand and flatter load profile of hybrid plants also puts owners in a favorable position for negotiating lower off-peak electric rates.

Hybrid cooling systems give you the best of electricity and natural gas in a deregulated world.   The following case studies demonstrate what happens when gas technologies are applied to real-world situations.

Case Studies:

Hospital saves space and dollars with YORK®prescription – Washington, DC

York package of steam-turbine and electric chillers plus construction, project management and financing is just what the doctor ordered.

CNN Center Cashes In On Energy Savings With New Hybrid Cooling Plant – Atlanta, GA

CNN is making news and taking advantage of real-time pricing by replacing one of its three electric centrifugal chillers with a natural gas engine-driven chiller.

Hybrid cooling offers these important advantages:

  • Lowers overall cooling costs
  • Fuel-choice flexibility during service interruptions
  • Equipment first-cost offset by savings
  • Paybacks ranging from 1 to 5 years
  • Strengthens electric rate negotiating position due to decreased load profile
  • Improved redundancy
  • Automated controls optimize plant efficiency
